All callers were passing in "a.out" or garbage so a sensible default works fine
here as a cleanup.
This also brings about the possibility of adapting the value based on the
driver's compatibility mode in future.
The setting can still be changed via Driver::DefaultImageName as needed.

The loop body used to contain a switch statement; it looks like r96685 replaced
that with an if/else if/else but accidentally left one of the three break
statements from the switch behind, skipping the clang_disposeString() call
for replacements (and the rest of the loop too, which apparently doesn't make
a differences for the test cases we have).

This too might possibly the last leak in clang (PR19521).

r144269 changed clang_disposeDiagnostic() to be a no-op, but didn't update
code completion diagnostics. Let CXCodeCompleteResults store all diagnostics
returned by clang_codeCompleteGetDiagnostic() and then free them up in
clang_disposeCodeCompleteResults().
Code completion diagnostics referred to data stored in CXCodeCompleteResults
before already, so it wasn't possible to refer to the results of
clang_codeCompleteGetDiagnostic() after clang_disposeCodeCompleteResults()
before this change already -- hence this should be a safe, backwards-compatible
change.
Leak found by LSan, fixes PR19690.
llvm-svn: 208454
this is wasteful, blah blah, but this is a test utility only. It turns
out that without doing this, libxml2 will always leak a bunch of the XML
data, and that is causing failures with LSan. This is also quite a bit
simpler and I don't think it is slow enough to really be a show stopper.
If someone yells about the runtime of c-index-test, we can do other
things to try to mitigate it, but the current strategy wasn't working
well.

It's possible that the "comment AST" may be replaced or split out in the
midterm, any anyway this makes the headers easier to read.
Developers don't currently need to include "clang-c/Documentation.h" explicitly
and there's no macro to test for availability yet.
The raw comment and brief comment accessors have been kept in Index.h though
brief support may also move here as a separate proposal.
This is not a deprecation, just a gentle separation of concerns as we look to
simplify the built-in representation of comment nodes and support external
comment processors.
llvm-svn: 207392
The change was landed without review or test cases.
It trivially broke almost any stable application checking for Severity >=
CXDiagnostic_Error or indeed any other kind of severity comparison upon
encountering a 'remark'.
Mapped to CXDiagnostic_Warning until a workable solution is proposed to the
list that preserves API stability.
(It's also not clear why the rest of r202475 wasn't simply implemented as a
modifier to the existing 'warning' level.)
llvm-svn: 207319
A CursorPlatformAvailability can have several "unavailable" attributes, don't
leak all but the first. I'm not sure if there can be several "deprecate"ds too,
but add the same logic there to keep the two code paths looking the same.
llvm-svn: 207076
We don't need the ASTContext for the diagnostics, only the language
options, which we can get from the compiler invocation. It worries me
how many categorically different states the ASTUnit class can be in
depending on how it is being constructed/used.
llvm-svn: 206909
Update clang to use the InstrProfReader from LLVM to read
instrumentation based profile data. This also switches us from the
naive text format to the binary format, since that's what's
implemented in the reader.

The YAMLParser has its own escaped string representation, and does not
handle octal escape sequences. When writing the virtual file system to a
YAML file, use yaml::escape().

The idea is to give visibility to more type kinds, especially for getting
a better grasp of what appears as unexposed type kind with libclang.

Code review feedback from Eric Christopher on r204261.
I didn't want to go into too much detail (the revision history should
provide the full stuff) - but I can add more if that's preferred.
Also moved this up to right by the construction of the MCAsmInfo so
there's less chance that other things might sneak in in between.
llvm-svn: 205267
For those playing at home this produced some fairly subtle behavior. The
sections created in InitMCObjectFileInfo were created without compressed
debug info (a mistake, but not necessarily /broken). Since these
sections were almost always referenced by the existing MCSection object,
this almost worked.
This got weird when we got to handling the relocations for a section.
See ELFObjectWriter::WriteSection where we compute the true section for
a relocation section by simply stripping the ".rela" prefix and then
looking up that section - doing so hit the compression codepath, looked
up .zdebug_blah and found a newly constructed empty section... thus,
things got weird.
This is untestable without a cross-project test (let me know if people
would prefer that to no testing).

These don't seem to have any real point. Let's start with
IndexingContext. I can't come up with any conceivable reason to have
many hundereds of thousands of these alive in an address space which
would make the 4x difference in allocated (but unused) memory for the
string scratch buffer a significant memory usage problem.
The EditedSource one is somewhat more surprising. This is an 8x increase
in the memory allocated (but not used) per editted source file. However,
for this to realistically be a problem, you would need to have over half
a million editted source files in a single address space, and even that
would only really have problems on 32-bit Windows where you really only
have 2gb of virtual address space. And what's more important, the fix to
this if it is actually an issue shouldn't be to shrink the allocator's
size, it is to pass a single allocator into *many* edited source file
objects and let them share the memory.
These were the only two uses of custom sized BumpPtrAllocators
(excluding ones in the JIT using a custom allocation strategy) in all of
LLVM, Clang, LLD, LLDB, or Polly. I don't think we actually need this
complexity in the primary BumpPtrAllocator at all and am planning to
remove it.

Because neither ' ' nor '-' is alphanumeric, \b won't match between them!
Since in this case we know our output is coming from a -### invocation,
we should always have spaces on both sides of the flag we're trying to match,
"-cc1".

This updates CodeGenPGO to use the ProfileDataReader introduced to
llvm in r203703 and the new API for writing out the profile introduced
to compiler-rt in r203710.

This is a reapplication of r203236 with modifications to the definition of attrs() and following the new style guidelines on auto usage.

An option with the same name already exists in the makefile build.
The name CLANG_IS_PRODUCTION is historical. We should probably change it, but
should change the configure build at the same time.
llvm-svn: 203325
a missing include from CLog.h.
CLog.h referenced most of the core libclang types but never directly
included Index.h that provides them. Previously it got lucky and other
headers were always included first but with the sorting it ended up
first in one case and stopped compiling. Adding the Index.h include
fixes it right up.
llvm-svn: 202810
Serialized diagnostics were accidentally using the AST diagnostic level values
rather than a dedicated stable enum, so the addition of "remark" broke the
reading of existing serialized diagnostics files. I've added a .dia file
generated from Xcode 5's Clang to make sure we don't break this in the future.
llvm-svn: 202733
A 'remark' is information that is not an error or a warning, but rather some
additional information provided to the user. In contrast to a 'note' a 'remark'
is an independent diagnostic, whereas a 'note' always depends on another
diagnostic.
A typical use case for remark nodes is information provided to the user, e.g.
information provided by the vectorizer about loops that have been vectorized.
This patch provides the initial implementation of 'remarks'. It includes the
actual definiton of the remark nodes, their printing as well as basic parameter
handling. We are reusing the existing diagnostic parameters which means a remark
can be enabled with normal '-Wdiagnostic-name' flags and can be upgraded to
an error using '-Werror=diagnostic-name'. '-Werror' alone does not upgrade
remarks.
This patch is by intention minimal in terms of parameter handling. More
experience and more discussions will most likely lead to further enhancements
in the parameter handling.
